IMPROVEMENT IN ROCKING-CHAIRS.

Specification forming part of Letters Patent No. 207,135, dated August 20, 1878; application filed October 6, 1877.

To all whom it may concern:

Be it known that I, WENDELIN SENG, of Chicago, county of Cook, and State of Illinois, have invented a new and useful Improvement in Stand Rocking-Chairs, of which the following is a specification, reference being had to the accompanying drawings, illustrating the improvement.

The present invention relates to an improvement in rocking-chairs which are provided with stands for the support of the rockers, and on which the chairs are rocked.

Its nature, in brief, consists in a lock-bar provided with a spring-latch placed through the upper parts of the forward legs of the chair, and provided with notched catches extending down so as to look into the front round of the chair and hold the rockers in fixed positions relative to the stand.

In the drawings, Figure l is a sectional elevation on line m, Fig. 2; Fig. 2, asectional elevation of the seat-frame, rockers, and stand of the chair, taken on line y, Fig. 1; Fig. 3, an enlarged vertical section of that end of the lock-bar containing the spring-catch in position in the end of the rocker; Fig. 4, an enlarged elevation of one of the studs to which the coil-spring is attached; Fig. 5, an enlarged end elevation section of the rubber roller, which forms a stop for the stirrup attached to the rocker.

A represents the stand, and B the rocker and G D O D, the rounds and slats connecting these parts in the ordinary manner of constructing this kind of chair. I represents studs whichare used to support the ends of the coil-sprin g H, and which have necks n for that purpose, and screw-threads to fasten to the stand and rockers, and a mortise, L, to receive a lever to turn the stud into the wood.

To each rocker is attached a stirrup, G, which is provided with a slot considerably larger than the roller J, that the rocker may on one or two sides as stationary rubber would; The springs H hold the rockers down to the stand in the usual manner, and the stirrupsi and catches E prevent the rockers from hav-l ing a lateral movement. A lock-bar, O, is; placed through the forward ends of the rockers so as to turn, and in one end of this bar there is placed a spring-catch, M, which looks into the rocker, and prevents the bar from turning when necessary to hold catches E ere-.- vatecl, as shown by dotted lines E. These catches are rigidly secured to the lock-bar C, so as to come fiat against the insides of the rockers and stand, as shown, and they are provided with notches on their front edges to lock on studs or screws F, projecting out from the insides of the stand legs or feet A. The lock-bar projects through the rockers B, and. the knob L holds it in place. The spring catch M, being in position outside of the chair, can be readily operated by the hand, so as either to bring the catches E down so as to lock on the screws F or be elevated, as shown;

by dotted lines E.

I claim and desire to secure by Letters Pat 1 ent- The roller (3, notched at its end, as shown, and provided with the latch-spring M, placed within said notch, combined with the catch E and rocker B, as set forth.
